A curtain hanging assembly that consists of a curtain assembly able to effect horizontal opening and closing of curtains, and includes two elastic motor units provided with elastic feedback. Interactive dynamics between the two elastic motor units, through linear linkage, respectively cause torque forces produced to be in mutual opposition, enabling the let down area of the curtains to be naturally fixed at any height position.

A blockout blind system includes side tracks fitted with brushes in conjunction with a pelmet fitted with flaps ensure no light can pass around the blind. The flaps and brushes have offset apertures either side of the blind to allow for airflow thus preventing the blind being sucked out or pushed in by open or leaking windows and air conditioning systems. The system also conceals the chain for operating the blind thus eliminating strangulation hazards for children and animals. The design allows the system to be fitted to existing roller blinds.

A valance kit and mounting assembly secure a valance adjacent a window frame. A mounting block is securable in a clamp ring cavity of the window frame and includes a snap connector on the frame side thereof and a valance groove in each of the top and bottom sides thereof. The valance grooves extend in a width direction across the mounting block and have a depth dimension parallel with a plane of the window opening. A valance assembly includes a plurality of shrouds that together define the valance. Each of the shrouds is provided with a pair of snap ridges disposed facing each other and spaced substantially corresponding to a space between the top and bottom sides of the mounting block. The snap ridges are sized and positioned to engage the valance grooves in a snap fit. The universal mounting block is suitable for mounting various types of window treatments.

The present invention is a bottom assembly for a breakaway door. The bottom assembly comprises a first mounting plate fixed on one of the faces of the breakaway door proximate to its bottom and a security edge formed of a loop of flexible material suspended from the bottom of the breakaway door. The security edge has a second tab sandwiched between the first mounting plate and the breakaway door to mount the security edge to the breakaway door. The loop of flexible material has an interior void at least partially filled with an internal cushion. The bottom assembly further includes a first padded bar including a bumper and a first tab extending from the bumper wherein the first tab is sandwiched between the first mounting plate and the breakaway door to mount the first padded bar to said breakaway door.

A rolling shutter mechanism and a method for protecting a rolling shutter assembly covering an opening. The rolling shutter assembly includes a shutter, guide rails, a shutter roller and a locking mechanism. The rolling shutter mechanism includes protecting means to cover the rolling shutter assembly. The protecting means include a protecting box covering the shutter roller, protecting frames covering the guide rails and a protecting unit covering the lower part of the shutter when it is in its closed position.

The retractable screen retention system is a guiding device for retractable screens that is sturdy, secured, and does not displace easily. To accomplish this, the system includes a track assembly, a guiding rail, and a sliding assembly. The sliding assembly further includes a retention housing and a weight bar. The design and components of the retention housing allows for movement of the weight bar and the retractable screen and yet keeps them retained in the system. Furthermore, the arrangement of the sliding assembly is designed to be flexible and doesn't allow it to come out of the track during deflective motions such as due to wind or some other physical impact. Thus, the system provides a track assembly with a guiding channel for the retractable screen that prevents the displacement of the retractable screen from the track while providing flexibility.
